The list of nuclear emissions is arranged in order from the greatest penetrating power to the least penetrating power is gamma ray, beta particle, alpha particle.
What is nuclear emission?
Nuclear emission is the emission of nuclear energy by the chemicals produced in factories.
Nuclear reactors do not produce air pollution.
Thus, the correct option is (4) gamma ray, beta particle, alpha particle.

Answer:
(4) gamma ray, beta particle, alpha particle.
Explanation:
Penetration power is the capacity of a radiation to pass through any matter.
the penetration power is inversely proportional to the mass of particles or radiation.
Out of the given three rays, gamma rays are lightest then beta and then alpha.
Thus penetration power of gamma rays is highest.
Then beta particles
Then alpha particles.

The smallest possible particle of an element is a atom. An electron has a charge identical to that of of a proton, but with the opposite sign.
What is atom?
The smallest unit of matter that may be split without producing electrically charged particles is the atom. It is also the smallest piece of substance with chemical element-like characteristics. Electric forces, which link electrons towards the nucleus of atoms, cause them to be drawn to any positive charge.
Space makes up the majority of an atom. The remainder is made up of a cloud of negatively charged electrons around a positively charged nucleus made up of protons and neutrons. An electron has a charge identical to that of of a proton, but with the opposite sign.
Therefore, an electron has a charge identical to that of of a proton, but with the opposite sign.

B: thermochemical reaction
C: nuclear reaction
D: chemical reaction

Answer: Option (C) is the correct answer.
Explanation:
When two nuclei and a subatomic particle like proton, neutron or high energy electron collide with each other then it results in the formation of two or more different nuclides.
For example,
Whereas in an electrochemical, thermochemical and chemical reaction there occurs change in number of electrons and not in number of protons or neutrons.
Thus, we can conclude that a change in the number of protons or neutrons occurs in nuclear reaction type of reaction.
A change in the number of protons or neutrons occurs inwhich type of reaction? A change in the number of protons or neutrons occurs innuclear reaction. The answer is letter C. The rest of the choices do not answerthe question above.

Answer:
Wurzite has a higher Madelung constant when compared with Sphalerite therefore Wurizite is more stable.
Explanation:
Zinc Sulphide is a chemical compound that exhibits polymorphism. This means Zinc Sulphide can exists in different forms as a compound. Zinc Sulphide has two common polymorphs named; Wurtzite and Sphalerite .
This two polymorphs are crystalline in structure. Wurtzite is hexagonal in shape while Sphalerite is cubic in shape.
Madelung constant was named after German Physicist Erwin Madelung. Madelung constant is dependent on the the way ions are arranged in a solid substance or molecule. It is used to calculate the amount of energy required to move an ion from one point to the another in a crystal substance.
Madelung constant for Wurtzite is 1.64132 and for Sphalerite is 1.63806. Due to the fact that Wurtzite has a slightly higher Madelung constant that Sphalerite, it tends to be more stable than Sphalerite.
